NAME
     rriinntt, llrriinntt, llllrriinntt - round to integral value

SYNOPSIS
     ##iinncclluuddee <>

     double
     rriinntt(double x);

     long double
     rriinnttll(long double x);

     float
     rriinnttff(float x);

     long int
     llrriinntt(double x);

     long int
     llrriinnttll(long double x);

     long int
     llrriinnttff(float x);

     long long int
     llllrriinntt(double x);

     long long int
     llllrriinnttll(long double x);

     long long int
     llllrriinnttff(float x);

DESCRIPTION
     The rriinntt() functions return the integral value nearest to x (according to
     the prevailing rounding mode) in floating-point format.

     The llrriinntt() and llllrriinntt() functions return the integral value nearest to x
     (according to the prevailing rounding mode) in the return formats speci-
     fied.  If the rounded value is outside the range of the return type, the
     numeric result is unspecified and the "invalid" floating-point exception
     is raised. A range error may occur if the magnitude of x is too large.

SSPPEECCIIAALL VVAALLUUEESS
     rriinntt(+-0) returns +-0 for all rounding modes.

     rriinntt(+-infinity) returns +-infinity for all rounding modes.

     All these functions raise the "inexact" floating-point exception if the
     result differs in value from the argument (except when they raise some
     other floating-point exception, such as "invalid").

STANDARDS     The rriinntt() , llrriinntt() , and llllrriinntt() functions conform to ISO/IEC
     9899:1999(E).
